the lock tongue 13 is stably fixed to the lock cylinder 12 through
the tooth angle belt, thereby achieving an effective combination
between the mechanical clutching structure and the intelligent
electronic control structure.
[0039] The present invention is installed in a simple way on the
mechanical letter lock cylinder 12 that is often used in the
market. With the rapid development of the Internet, mobile
intelligent terminals have become a necessity in life, and the
intelligent access control system has developed rapidly. Many
electronically controlled door locks and fingerprint locks are able
to be used with mobile intelligent terminals. While human inertia
is not replaced by full intelligence, when developing new
intelligent products, it is firstly consider that whether the
product meets the needs of different age groups, such as the
elderly or users who have not yet used mobile intelligent
terminals. Therefore, in addition to being compatible with the
existing traditional key unlocking method, this design is able to
be optimized during use, and be manipulated with a more convenient
mobile intelligent terminal without contradiction in use.
[0040] According to the preferred embodiment of the present
invention, the intelligent electronic control structure further
comprises a battery 26, wherein the cover plate 24 has a battery
slot 253, the battery 26 is snapped within the battery slot and is
electrically connected with the PCB 21, a battery cover 27 is
located above the bottom plate 25 for replacing the battery 26 and
is in detachable connection with the bottom plate 25.
[0041] According to the preferred embodiment of the present
invention, the intelligent electronic control structure further
comprises an LED (light emitting diode) lamp holder 28 for
monitoring letter box status and an infrared distance sensor 29 for
continuously detecting whether there is a letter in the letter box,
wherein: the LED lamp holder 28 and the infrared distance sensor 29
are electrically connected with the PCB 21, and lamp beads 281 of
the LED lamp holder 28 and the infrared distance sensor 29 are
displayed on a surface of the bottom plate 25.
[0042] According to the preferred embodiment of the present
invention, the PCB 21 comprises a wireless control module which is
communicated with the external mobile intelligent terminal for
wireless connection and an information sending module for sending a
letter prompt message to the external mobile intelligent terminal,
wherein the wireless control module is a Bluetooth connection
module or LAN connection module.
[0043] When the letter box is opened, the intelligent lock will
judge whether the door of the letter box has been closed according
to the change of luminosity. When the luminosity in the letter box
returns to the original luminosity, the intelligent lock of the
letter box will be automatically locked. In addition, the infrared
distance sensor 29 of the intelligent lock constantly detects
whether there is a letter is put into the letter box and prompts
the user in three different ways. The first way is to use the long
bright LED indicator light on the intelligent lock; the second way
is to detect for short distance and push notification information
to the user's mobile phone when the user opens the mobile
intelligent terminal application; the third way is to directly send
the letter notification information to the application of the
mobile intelligent terminal through the cloud via the intelligent
integrated terminal.
[0044] The above disclosure is only a few specific embodiments of
the present invention, but the present invention is not limited
thereto, and any changes that can be made by those skilled in the
art should fall within the protective scope of the present
invention.
